Ugh, that's what I get for replying before my third cup of coffee. 

I was trying to bring up a 2.6.26-rt kernel on an IBM LS20 blade back in
January. It was a comparison experiement (MRG RT wasn't going to use a
2.6.26 kernel), so I didn't file a BZ or keep any of the data around :(.

I don't see this panic in the 2.6.24 series, nor do I see it in the
2.6.29 series, so it seems that I only saw it in 2.6.26.  I'll keep an
eye out for this behavior again, but still no complaint if this patch
gets dropped. 

Sorry for the noise.
